Burger King is a hamburger restaurant chain best known for its signature product, the Whopper. Founded in 1953 under the name of “Insta-Burger King” in Jacksonville, Florida, the company was taken over by franchisees David Edgerton and James McLamore in 1954 and renamed to Burger King. After a series of ownership changes, including a period as a public company from 2006 to 2010, Burger King is now majority-owned by 3G Capital of Brazil and operates over 14,000 restaurants in 79 countries.

BK, as the company is often abbreviated, is the second-largest hamburger chain behind McDonald’s, with a menu very similar to its main competitor. The chain differentiates itself from the market leader by offering flame-grilled meat and a smaller variety of menu items. Customers can also make special orders, omitting ingredients or adding extras. The Whopper remains the most successful product, being sold 2.1 billion times a year across the world.
